Can not set cudnn_conv_algo_search on ort 1.6

[KhanhNGit]

I'm currently using systems run on onnxruntime 1.6.0, cuda 10.2 and cudnn 8.
How can i set "cudnn_conv_algo_search"?
I have tried the declare the same as the docs: "self.session = onnxruntime.InferenceSession(self.model_file, providers=[('CUDAExecutionProvider', {"cudnn_conv_algo_search": "HEURISTIC"}), 'CPUExecutionProvider'])" but i got the error:
